Updated mysql packages that fix a security flaw are now available for Red
Hat Enterprise Linux 4.

This update has been rated as having moderate security impact by the Red Hat
Security Response Team.

MySQL is a multi-user, multi-threaded SQL database server. MySQL is a
client/server implementation consisting of a server daemon (mysqld) and
many different client programs and libraries.

A flaw was found in the way MySQL handled case sensitive database names. A
user with the ability to create databases could gain unauthorized access to
other databases hosted by the MySQL server. (CVE-2006-4226)

This flaw does not affect the version of MySQL distributed with Red Hat
Enterprise Linux 2.1, 3, or 5.

All users of the MySQL server are advised to upgrade to these updated
packages, which contain a backported patch which fixes this issue.
